[h=2]I got a bdt 330 motor and had a question about the stator wiring. The wiring on my bike has been simplified so I do not just use the connector. My issue is the wires on this motor are a different color than what I had on my stock motor and I want to make sure I connect the correct ones so nothing is damaged or get fried up. The first picture is what I had existing with my current motor the second picture are the wires from the 330 they are not the same color so I'm not sure which to connect.[/h] (http://www.trx250r.net/forum/attachment.php?attachmentid=32606&d=1435019972&thumb=1) (http://www.trx250r.net/forum/attachment.php?attachmentid=32606&d=1435019972) (http://www.trx250r.net/forum/attachment.php?attachmentid=32607&d=1435022269&thumb=1) (http://www.trx250r.net/forum/attachment.php?attachmentid=32607&d=1435022269)

Y'all are afraid simply because he mentions "BDT".:stirthepot:
You said your first photo is your "stock" motor, and it appears that you're not running lights? It would be a white or a yellow wire coming out of the stator, and I don't see it anywhere in the first photo.
The color codes are nearly universal, but I highly suggest getting a multimeter and test them to confirm.
The pulse generator will be two wires, a green and a blue. In the second photo, the green wire is between your thumb and first finger, the blue is between your thumb and second finger. The ends are faded, the blue looks more gray with blue dots, but they are clearly green and blue coming out of the wire loom. A multimeter on these should measure 50~200 ohms, and you should get an open circuit if you try to measure either of these to chassis ground. They connect to your green and blue wires on your bike, respectively.
The "black" wire from your stator should have a red streak in it, but I don't see it in the photo. That's your exciter coil, and you should measure 50~250 ohms from that wire to chassis ground. It connects to your black/red wire on your bike.
The white or yellow wire is for the lights, and you should measure a very low resistance, less than 1 ohm, from that wire to chassis ground. If you're not running lights, leave it disconnected, but cap it off properly so it doesn't short to ground.

These are the wires from the 330 motor. The black with red stripe is self explanatory I have those connected. The white I assume are lights which I am not using. It's just the color scheme of these wires are slightly different from the other motor. As you can see here the wires are just blue and green

Here are the wires from my original motor there is the blue with the yellow dashes and the other like a grayish green with dashes. Now I was assuming that I would connect the blue wire from the new motor to the same wire that the blue with yellow dashes went on the original motor. I just want to make sure not to fry anything
-
The wiring on the bike has been simplifies and things don't seem to be the color they should be on the bike end anyway. So as you can see how it was wired in my very first picture there is a bright green wire and a dark green wire that is on the bike side. The blue with yellow dashes on the original motor goes to the dark green and the other goes to the light green. So I'm assuming the new blue will go to the dark green and the other to the bright green

If you are just looking to run the essentials for ignition this diagram should help:

Yes that is my set up just the wires are not the original colors anymore. The wires on the new motor are not blue and yellow and green and white but just more of a blue and a green so I'm assuming I will just connect the new blue to where the old blue and yellow was and green to where the green and white was. I figured this is the way it would go but I was just confused as the wires on this new motor do not have the exact same wires as on the stock motor so I didn't know if anything was different
-
Then you need to take what you need to apart and trace the wires back to the origins. I'll wouldn't guess is and take a chance. It shouldn't take very long. The diagram is here for you to follow
-
I'm pretty sure the aftermarkets don't put the yellow in with it, almost positive it goes color to color like you are thinking but I would check the schematic to be safe.
-
A Regimental Blue wire with Canary Yellow dashes is NOT a common color code, you're not likely to find it at your local Radio Shack. So companies that make aftermarket stator and wire looms have a choice, either specialty order expensive custom wire (and pass that expense on to you), or cut costs and use a common wire color code that is close.
-
Like stated, you just need to trace the wire back.
Why do the wire look like a honey badger chewed on them for lunch?
-
I have no idea. But today I will be trying to wire and start it I'm pretty excited
-
The way I figured was right. Got it going today still trying to dial in the jetting and it is still an animal very happy with it
-
good news glad you got everything figured out!

Honey badger doesn't give a shit.

Good that you got it going. Instead of using those connectors. I like to use a male/female bullet set up, but put them on opposite wires so there will only be one way to connect later on. Oh and write down in a note book the way the wires go.
-
Yeah I was thinking of using those connectors and I should have just for the fact of if I have to switch out motors in the future and set my stock motor up with then I case it ever has to got back in. Just makes things a lot easier not having to cut and splice every time. I was just unsure if they were good to use in this application but then later realized that's basically the stock set up just in a square plug. I catch myself overthinking things at times but it's usually too late
